Heart and Love charm, with a clasp at the top for attachment to the strand of either a Window Crystal or a terrarium. I make the beaded strands with a connector bead charm bail to hold charms onto Crystal beaded strand. The charms can be used for anything that the clasp can connect to. If you want to use another way like attach to keychains, boots, etc. the character of the charms adds to anything you want to put them on.
